ABSTRACT

Pseudoaneurysms of the extracranial vertebral artery are extremely rare due to their deep location and the anatomical protection of this artery. They can be caused by cervical traumas (firearm injuries, sports, hyperextension of the neck and iatrogeny). The authors report the case of a patient who developed a giant pseudoaneurysm of the extracranial vertebral artery after surgery for the removal of a tumor of the cerebellopontine angle in which surgical lesion of the artery occurred. Treatment was performed by endovascular approach. Literature is reviewed and comments are made on the physiopathogeny of the lesion and the different forms of treatment.

Key words:aneurysm, vertebral artery aneurysm.endovascular treatment


RESUMO

Os pseudoaneurismas da artéria vertebral extracraniana são extremamente raros pela localização profunda e proteção anatômica desta artéria. Podem ser ocasionados por traumas cervicais (ferimentos por armas de fogo, esportes, hiperextensão do pescoço e iãtrogenias). Os autores relatam o caso de um paciente que desenvolveu um pseudoaneurisma gigante da artéria vertebral extracraniana após cirurgia para retirada de tumor de ângulo ponto cerebelar em que ocorreu a lesão cirúrgica desta artéria e cujo tratamento foi endovascular. A literatura é revisada e são feitas considerações sobre a fisiopatogenia da lesão e as várias formas de tratamento.

Palavras-chave: aneurisma, aneurisma da artéria vertebral, tratamento endovascular
